1 Bridgelux V8 Array Series Product Data Sheet DS41 BXRE-xxx0800-A, BXRE-xxx0800-B Introduction The Bridgelux V8 LED Array products delivers high quality light in a compact and cost-effective solid-state lighting solution. These products can be efficiently driven at twice the normal current, enabling design flexibility not previously possible. This high flux density light source is designed to enable a wide range of sub 1000 lumen directional luminaires and replacement lamps for commercial and residential applications. The V8 LED Array light engine is available in multiple electrical, CCT and CRI combinations providing considerable design-in flexibility and energy efficiencies. Lighting system designs incorporating these LED Arrays deliver comparable performance to that of Watt incandescent and halogen and 7-13 Watt compact fluorescent based luminaires they provide increased system level efficacy and longer service life. Typical applications include replacement lamps, task, accent, spot, track, down light, wide area, security, and wall pack.

3 Typical Product Features Bridgelux arrays are fully engineered devices that provide consistent thermal and optical performance on an engineered mechanical platform. The V8 array is the smallest chip-on-board device across all of Bridgelux s LED Array products. The arrays incorporate several features to simplify design integration and assembly.

4 Lumen Maintenance Characteristics Bridgelux projects that its family of LED Array products will deliver, on average, greater than 70% lumen maintenance after 50,000 hours of operation at the rated forward test current. This performance assumes constant current operation at the nominal drive current with case temperature maintained at or below 85 C. For use beyond these typical operating conditions please consult your Bridgelux sales representative for further assistance. These projections are based on a combination of package test data, semiconductor chip reliability data, a fundamental understanding of package related degradation mechanisms, and performance observed from products installed in the field using Bridgelux die technology. Bridgelux conducts lumen maintenance tests per LM80. Observation of design limits is required in order to achieve this projected lumen maintenance. Environmental Compliance Bridgelux is committed to providing environmentally friendly products to the solid state lighting market. Bridgelux LED Arrays comply with the European Union directives on the restriction of hazardous substances in electronic equipment, namely the RoHS directive. Bridgelux does not intentionally add the following restricted materials to LED Array products: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE). UL Recognition Bridgelux secures UL recognition for all the LED Array products. Please refer to the UL file E for the latest list of UL recognized Arrays. Bridgelux uses UL recognized materials with suitable flammability ratings in the LED Array to streamline the process for customers to secure UL listing of the final luminaire product. CE Recognition In accordance with the relevant European Union directives, the family of LED Array products conform to the applicable requirements of the IEC/EN 62031:2008 (LED Modules for General Lighting Safety Specifications) and IEC 62471:2006 (Photobiological Safety of Lamps and Lamp Systems). Bridgelux maintains a CE Declaration of Conformity statement on its website and displays the CE mark on product packing labels. Minor Product Change Policy The rigorous qualification testing on products offered by Bridgelux provides performance assurance. Slight cosmetic changes that do not affect form, fit, or function may occur as Bridgelux continues product optimization. Case Temperature Measurement Point A case temperature (T c ) measurement point location is included on the top surface of the Bridgelux LED Arrays. The location of this measurement point is indicated in the mechanical dimensions section of this data sheet. The purpose of this measurement point is to allow the user access to a measurement point closely linked to the true case temperature on the back surface of the LED Array. Once the LED Array is installed, it is challenging to measure the back surface of the array, or true case temperature. Bridgelux has provided the case temperature measurement location in a manner which closely ties it to the true case temperature of the LED Array under steady state operation. Deviations between thermal measurements taken at the point indicated and the back of the LED Array differ by less than 1 C, providing a robust method to testing thermal operation once the product is installed.

5 Cautionary Statements CAUTION: CONTACT WITH OPTICAL AREA Avoid any contact with the optical area. Do not touch the optical area of the LED Array or apply mechanical stress to the yellow phosphor resin area it could damage the LED Array. Optics and reflectors must not be mounted in contact with the yellow phosphor resin area (LES) or the white ring that surrounds the yellow phosphor area. Using the white ring to secure optics can result in damage to the LED Array as the ring is not designed to act as a mechanical locating feature. Optical devices may be mounted on the top surface of the LED Array substrate outside of the white ring maximum OD as specified in the product data sheet. Use the mechanical features of the LED Array substrate edges and/or mounting holes to locate and secure the optical device as needed. CAUTION: EYE SAFETY Eye safety classification for the use of Bridgelux LED Arrays is in accordance with IEC specification EN62471; Photobiological Safety of Lamps and Lamp Systems. Bridgelux LED Arrays are classified as Risk Group 1 (Low Risk) when operated at or below their rated test current. Please use appropriate precautions. It is important that employees working with LEDs are trained to use them safely. CAUTION: RISK OF BURN Do not touch the LED Array or resin area during operation. Allow the LED Array to cool for a sufficient period of time before handling. The LED Array may reach elevated temperatures such that it can burn skin when touched. CAUTION: CHEMICAL EXPOSURE HAZARD Exposure to some chemicals commonly used in luminaire manufacturing and assembly can cause damage to the LED Array. Please consult Application Note AN11 for additional information. Bridgelux V8 Array Product Data Sheet DS41 (10/11/2013) Page 5 of 24
